Glossary / Back-End


Back-end refers to the part of a software application or website that is responsible for processing and storing data. It is the behind-the-scenes functionality that is not visible to the user but is essential for the proper functioning of the application. In web development, the back-end typically consists of a server, a database, and an application that handles requests from the front-end (the user interface) and processes the data. It involves tasks such as data validation, database management, server-side scripting, and security. Back-end development often involves programming languages such as Python, Java, Ruby, or PHP, and frameworks like Django, Spring, Ruby on Rails, or Laravel. It also includes working with databases like MySQL, PostgreSQL, or MongoDB. The back-end is responsible for handling user authentication, managing user sessions, processing forms, and interacting with external APIs or services. It ensures that the data is securely stored and retrieved, and that the application functions smoothly. Overall, back-end development focuses on the logic and functionality of an application, while front-end development deals with the user interface and user experience. Both are crucial for creating a complete and functional software application or website.
